I have the RSB110-070 dome and RDP143 display. The display powers up and screen shows range rings, text, etc. All key functions work. Antenna rotates when transmit is selected. But no target image. Cable appears to be connected properly and power supply as well. Unit functioned correctly not long ago, only thing I changed was connecting power supply to a new breaker and bundling the too long cable to stow. The unit is stand alone and not connected to a network. What's going on? Thanks

Based on what you describe, I suspect the scanner cable. If you transmit the radar and turn off/down all the filtering and sea clutter, then turn you gain on Manual and maximum.. can you speckle your screen with noise or is the screen still blank? You don't get any errors or alarms correct?
If you press the ALARM button it will show you any alarms. Normally will will also make sounds if someone hasn't turned off the alarm button. By the sound of it, the small coax wire within the scanner cable is broken that goes between the scanner and the display unit. That wires passes the radar video. You don't appear to be getting any.
No that wouldn't keep the radar from working. That is because it sees no GPS data.
I would ohm out the one you have before taking that step. New cables are no longer available for that ~2002 radar. Raw cable and some items still are available new. Used cable might be okay but I still would not recommend anything be purchased until verified bad.
Page S-1 of the installation manual has a full wiring diagram that shows the small coax video line as part of the overall cable wiring.
Yes, that is the video line.
Fixed it! Pin 3 in the dome connector had backed out of the connector somehow. Snapped it back in and everything works great. Thanks for the help. Can you tell me how to shut off the audible alarm that goes off when the display discovers that there is no GPS hooked up? Thanks
Hit the button labeled ALARMS and turn OFF all audible alarms.
